Posting due to the sheer volume of questions/antipathy I’ve been getting about this topic.
I rank reset my chronolinker to be a cryochrono. Two days later, at maintenance, I began crashing and having serious FPS drops whenever frost pillar or henge were cast.
My solution to this was to verify steam cache. Fair warning: This process does take a bit of time, because if you do it correctly, the ToS patcher will completely redownload a bunch of its patches.
Make sure your game is closed before you do this. It will not impact the install of any addons you have, but will roll back all your loading screens to the original contest set.
1.) In Steam, go to your library. On the left side is your list of games. Right click Tree of Savior, and click on Properties at the very bottom.
2.) Go to the third tab, called Local Files.
3.) Click on “Verify Integrity of Games Files…”
Let it run its course. When you try to run the game next, the patcher should begin downloading old patches again and, depending on your internet speed, this could take a fairly long time.
My FPS in TBL is pretty average, but here’s a random match from today where you can see that I don’t suffer massive freezing up upon casting frost pillar:
(As you can see, my loading screens rolled back to the old ones after verifying).
